Feb 13, 2003

PRINCETON, NJ February 13, 2003 - ITXC Corp (NASDAQ:ITXC) announced today that it has chosen the Cisco AS5000 Universal Gateway and PGW 2200 Softswitch Voice Over IP (VoIP) offerings as the basis for the next generation of ITXC's worldwide inter-carrier voice network currently spanning over 175 countries. ITXC is one of the world's largest carriers in terms of minutes of international voice traffic carried and is, according to TeleGeography 2003, the market share leader in international VoIP. VoIP use in international calling is growing rapidly; TeleGeography estimates that it now accounts for 10% of international phone-to-phone calling, up from just 6% a year ago.

"More and more often carriers use ITXC for all or part of their traffic," said ITXC Chairman and CEO Tom Evslin. "Carriers have found that simplifying their networks by relying on ITXC has resulted in lower cost of ownership and higher reliability than managing a multitude of vendors in a complex routing table. Similarly, ITXC has found that relying on Cisco for most of its equipment needs results in lower costs and higher reliability as well as multi-vendor interoperability, which is important to ITXC and its customers. Our purchasing and support relationship with Cisco helps us deliver the very high reliability our carrier customers require when our network is the only route for their traffic."

"We are pleased that ITXC has chosen Cisco as their vendor for the next generation of their network and proud to have helped ITXC achieve its current success," said Charlie Giancarlo, senior vice president of Cisco Systems, Inc. "ITXC's focus on quality and scale, combined with Cisco VoIP technology, provide carrier customers a highly reliable network for their voice traffic."

In addition to their interoperability design features, which allow ITXC to easily work with other VoIP equipment as well as global PSTN networks, ITXC chose Cisco AS5000 gateways for their high density and feature-richness. The Cisco PGW 2200 Softswitch enables SS7 interconnect worldwide, eliminating unnecessary paths through TDM switches.

ITXC's patented BestValue RoutingTM technology uses the Cisco VIA equipment to route voice calls with consistent carrier grade quality across the public Internet. ITXC's carrier and prepaid calling card customers benefit from the low capital and operating costs possible on the Internet without sacrificing the quality their subscribers require.

ITXC has been accepted to the Cisco Powered Network program for their IP telephony services. Cisco sells equipment to carriers worldwide and ITXC sells international call completion to these same carriers. ITXC interfaces with Cisco equipment and Cisco-interoperable equipment, including that from VocalTec and others at many carriers. ITXC often installs its own Cisco equipment at carrier locations. The companies are collaborating in marketing and sales activities for existing and new products and services aimed at the carrier segment.
